KP
The KP series vertical FRPP submerged pump is a high-performance tank-mounted pump specifically engineered for reliable liquid extraction and circulation in corrosive industrial environments. Featuring a fully submerged design, this pump eliminates priming challenges and maintains stable operation even with fluctuating liquid levels in storage tanks and process vessels. Built with advanced injection molding technology, it offers exceptional chemical resistance and durability, making it an essential fluid handling solution for facilities processing acids, alkalis, and various chemical liquids. Its compact footprint and easy installation make it ideal for retrofitting existing systems or integrating into new production lines.
Superior Corrosion Resistance: Constructed from premium FRPP, CFRPP, CPVC, or PVDF materials, the FRPP tank pump withstands a broad spectrum of aggressive chemicals. Material selection is precisely matched to liquid concentration and operating temperature for optimal performance.
Unlimited Dry-Run Capability: Equipped with a dry-type liquid seal, the pump can operate continuously without liquid, preventing costly downtime and component damage caused by accidental tank depletion.
Lightweight Modular Design: The all-plastic construction significantly reduces weight compared to metal equivalents, simplifying installation and minimizing structural stress on tank walls.
Secure Impeller Assembly: The impeller is secured with a C-type snap ring, eliminating radial movement or loosening during high-speed operation and ensuring long-term reliability.
Effective Acid Gas Protection: The integrated venting system expels chemical vapors between the extension plate and motor base, preventing corrosion of motor bearings and windings.
